New Technology Making a Real Difference for the Environment
Today’s headlines are often filled with concern about the climate, but behind the scenes, a different story is being written — one of steady progress through new technology. The World Economic Forum’s 2025 list of Technology Pioneers highlights companies that are not only creating new tools, but also changing how we solve environmental problems.
Many of these companies are tackling the issue of emissions in unexpected ways. Rubi Laboratories is working on a process that uses carbon dioxide — usually seen as a waste product — to make materials like textiles. Similarly, Emvolon captures methane, another harmful gas, and turns it into cleaner fuel. Arcadia eFuels is developing aviation fuel from seawater, offering a cleaner option for air travel.
Other companies are finding new ways to generate power by using natural processes. Sweetch Energy, for example, creates electricity from the small energy that forms when freshwater meets saltwater. It’s a quiet but effective method that doesn’t require massive infrastructure.
The tech sector is also getting a sustainability update. Traditional data centers consume a large amount of electricity. LightSolver is developing optical computers that run on light instead of electricity, using far less energy. Another company, Starcloud, has proposed placing data centers in space where they can rely on constant solar power.
In agriculture, precision is replacing guesswork. With satellite data, farmers can now better manage their use of water, fertilizers, and other resources. Companies like NARA Space are even using small satellites to detect methane from farms, helping to reduce emissions from agriculture — a less visible but significant source of pollution.
Nuclear power is also evolving. A French company called Jimmy is building small, safe nuclear reactors that provide clean heat for industries. Unlike traditional reactors, these are compact and built for specific purposes, helping reduce carbon emissions from large-scale manufacturing.
These examples show that real solutions are already being created and tested. What ties these projects together is a clear focus on practical impact. These innovators are not waiting for long-term policies or major shifts — they are building better options now.
The 2025 Technology Pioneers represent a group of people using their skills to address environmental problems head-on. Their ideas are not just imaginative — they’re useful, measurable, and already making progress. While climate change remains a major challenge, these developments show that we have options, and that meaningful change is already underway.
Back Rainforest Loss and the Global Impact
World Rainforest Day highlights a growing environmental concern—widespread rainforest destruction. Often called the "Green Lungs of the Earth," rainforests are essential for maintaining global ecological balance. However, large areas of these forests are disappearing rapidly due to human-driven activities.
Currently, the rate of deforestation is approximately 18 football fields per minute. In a single year, more than 78 million hectares of rainforest are lost. This ongoing destruction not only reduces tree cover but also weakens a key natural defense against climate change. Rainforests store carbon dioxide, and when they are cut or burned, that carbon is released into the atmosphere, increasing the planet’s temperature.
In addition to regulating climate, rainforests provide habitats for about half of all land-based species. Every cleared section of forest leads to habitat loss and the extinction of many species, some of which have never been scientifically recorded. An estimated 137 species of plants, animals, and insects go extinct daily as a direct result of deforestation.
Primary causes of this destruction include agricultural expansion for livestock, soy, and palm oil, as well as logging, mining, and land development. Fires, often set intentionally, escalate beyond control and cause widespread damage to ecosystems that have taken centuries to form.
Rainforest loss affects more than local environments. It contributes to extreme and unpredictable weather patterns, including longer droughts, intense flooding, and severe storms. A cycle of destruction is formed: deforestation increases global temperatures, which in turn causes more wildfires and accelerates the climate crisis.
This issue extends beyond environmental concerns. It threatens global food systems, clean air, and water supplies. Addressing the crisis requires strong environmental regulations, international cooperation, and the leadership of Indigenous communities who have long safeguarded these ecosystems.
World Rainforest Day is a critical reminder of the urgent need for action. Without effective steps to stop deforestation, the consequences will become more severe and more immediate for ecosystems, economies, and all life on Earth.
Back Tree Plantation, Clouds, and Climate Change
Many people once thought planting trees offered a simple solution to a warming world, giving a comforting feeling of doing good. However, new scientific discoveries show the huge size of climate challenges, far beyond what tree planting alone can fix. At the same time, worrying new information about clouds reveals they are making the planet hotter in ways just beginning to be understood.
Understanding why more tree plantation cannot solve all climate problems is important. While tree planting certainly helps nature, new research proves it cannot make up for the massive amounts of carbon released from burning fossil fuels. To grasp the size of this problem, imagine needing a forest bigger than all of North and Central America combined just to offset the pollution from the world's biggest fossil fuel companies. This shows how unrealistic it is to rely only on tree planting. There isn't enough suitable land on Earth to soak up all the carbon being released. The cost for such a massive tree-planting effort would be around $11 trillion. That amount is more than the total value of the top 200 fossil fuel companies, making it financially impossible. Researchers have even found it is cheaper to leave fossil fuels in the ground than to burn them and then try to fix the damage with trees. Trees do absorb carbon as they grow, but their ability is limited. Carbon absorption slows down over time. Also, for trees to work long-term, they need to survive and grow to full size, which can be difficult because of things like wildfires, diseases, and changes in how land is used. It also takes decades for trees to grow big enough to absorb a lot of carbon. Emissions need to be cut right away, and waiting for trees to grow simply is not fast enough.
Planting huge areas with only one type of tree can also harm the environment. It can reduce the variety of plants and animals, use too much water, and potentially increase the risk of widespread pests or fires. Any tree planting efforts should be part of well-managed projects that use local plants and protect local wildlife. Focusing too much on tree planting can also distract from the main problem: the urgent need to drastically reduce greenhouse gas emissions from fossil fuels and factories.
Scientists stress that the main solution to climate change is switching to clean energy, using energy more efficiently, and stopping the cutting down of forests. Simply put, while planting trees is a valuable tool, it is not a complete solution. It cannot replace the urgent need to stop burning fossil fuels.
Now, consider clouds. Clouds are very important for controlling Earth's temperature. They act like a sunshade, reflecting sunlight back into space, and also like a blanket, trapping heat near the Earth's surface. However, recent research, including studies from Australia and NASA, shows that rapid cloud loss is a big reason for recent record-breaking global temperatures. When there are fewer clouds, especially low-level ones, less sunlight gets reflected back into space. This means more of the sun's energy is absorbed by Earth, leading to warming. Research suggests that in 2023, Earth reflected less sunlight than ever before, largely because of fewer clouds, which helps explain the unusually high temperatures seen.
Studies show that the decrease in clouds is particularly noticeable in low-level clouds, especially over certain parts of the northern oceans and tropical areas. These low clouds are very good at reflecting sunlight. The loss of these clouds can create a dangerous cycle: as the planet gets warmer, conditions might become less favorable for these reflective low clouds to form. This would lead to even more warming, possibly speeding up global warming significantly. It is also possible that efforts to reduce air pollution, which contains tiny particles that help clouds form, might be causing fewer low-level clouds. While cleaner air is good for human health, fewer of these particles could mean fewer "seeds" for clouds to form, leading to less reflective clouds or clouds disappearing faster. The warming air itself can also affect where clouds form, with changing wind patterns leading to fewer clouds in important regions.
Warmer ocean surfaces can also cause low-level clouds to disappear, creating a local cycle where ocean warming leads to cloud loss, which then leads to more sunlight being absorbed by the ocean, causing even more warming. While scientists are still studying the exact details of how clouds affect warming, the evidence strongly suggests that cloud loss is a significant factor in recent global warming that was previously underestimated. This means accurately predicting cloud formation and how much sunlight clouds reflect is vital for future climate forecasts and highlights the urgent need for complete climate action.
Both the idea that tree plantation alone can solve climate change and the worrying trend of clouds disappearing show how complicated and urgent the climate crisis is. There are no easy answers. A wide-ranging approach is needed, focusing on immediately cutting greenhouse gas emissions, managing land in a way that can be sustained, and continuing scientific research to deal with these connected environmental challenges.
Back Indian Environmental Performance: The Data Speaks
The "State of India's Environment 2025 in Figures" report, a joint effort by Down To Earth and the Centre for Science and Environment, provides a stark overview of India's environmental situation. It reveals that states nationwide are having real difficulty meeting key environmental benchmarks.
Not a single state managed to score 70 out of 100 for its environmental efforts. This widespread underperformance highlights significant challenges across all environmental measures. For instance, even Andhra Pradesh, the top-ranked state in the environmental category, still only achieved 68.38 out of 100.
A major concern is the handling of sewage. There's a huge gap between the amount of sewage produced and how much of it actually gets treated. This is a country-wide problem. Many states, even those typically performing well, are struggling in this area. For example, Andhra Pradesh treats less than 11% of the sewage it produces daily, placing it 18th among all 36 states and Union Territories for sewage management.
River pollution remains a serious issue. While a few states, like Andhra Pradesh, have seen fewer polluted river stretches, high levels of pollution are still common. Rivers such as the Vasishta show dangerously high levels of biochemical oxygen demand, far exceeding safe limits. Across the country, 27 states and Union Territories scored below 50 when their water quality was assessed.
Waste management efforts are also falling behind schedule. India is not on track to meet its 2026 goal for cleaning up old waste, having only managed to deal with half of it. Meanwhile, the amount of new waste being generated has increased sharply. For instance, electronic waste jumped by 147% in just seven years. Hazardous waste from industries also went up by 25% since 2017-18, leading to a significant rise in total hazardous waste. Even with bans on certain single-use plastics, plastic waste reached a record high in 2022-23.
Air quality is another major worry. People living in 13 Indian capital cities, including Delhi, breathed polluted air at least one out of every three days since 2021. This poor air quality has serious health consequences, with residents in 18 of 28 state capitals losing more years of their life due to air pollution than the average for their state.
The effects of climate change are clear. The report noted that the past year was the warmest on record. There was also a notable increase in heavy rains, floods, and landslides, occurring on 80 out of 90 days. These events caused 122 deaths and damaged over 24,000 hectares of crops.
Even the growth in forest cover has a catch. While India gained 16,630 square kilometers of forest between 2013 and 2023, nearly all of this increase occurred outside of official forest areas. At the same time, the country approved the use of 29,000 hectares of existing forestland for other purposes in 2023-24, the highest amount in nearly a decade.
Overall, the report shows that while there are minor improvements in some environmental areas, significant problems like sewage treatment and river health continue to hinder progress. This situation makes it clear that India needs to make protecting its environment a much higher priority, with strong and coordinated actions to prevent these worrying figures from getting worse.
Back A Simple Meal Can Shape a Better World
Sustainable Gastronomy Day, observed on June 18th, often goes unnoticed. It is not widely celebrated or highlighted in public conversations. However, it brings attention to something deeply important: the impact of everyday food choices on the environment, the economy, and cultural traditions.
Food does not appear on the plate by chance. Behind each ingredient lies a complex system involving agriculture, transportation, labor, and natural resources. Sustainable gastronomy focuses on improving this system by supporting farming methods that protect the environment, using resources responsibly, and valuing cultural food heritage.
Modern eating habits often ignore the environmental cost. Producing certain types of food, such as red meat, requires large amounts of water and generates harmful emissions. Transporting exotic produce across continents adds to pollution. Wasting uneaten food leads to the loss of energy, time, and natural resources used to produce it.
There are ways to reduce this damage. Choosing food from local farms helps cut down pollution from transport and supports local economies. Including more plant-based meals in diets can lower environmental pressure. Planning meals and storing food correctly helps reduce waste. Small steps taken daily can create meaningful improvements.
Traditional food practices in many cultures already reflect sustainable methods. These recipes rely on seasonal ingredients, avoid waste, and pass down cooking techniques that balance taste with responsibility. Returning to these practices strengthens cultural identity and supports sustainability.
Sustainable gastronomy encourages awareness, not perfection. A single ingredient chosen with care or one meal prepared with intention can be part of a larger solution. Each decision about food can contribute to healthier communities and a healthier planet.
Food connects people to the land, to one another, and to the future. On Sustainable Gastronomy Day, and every day, thoughtful food choices can lead toward a world that values both nourishment and responsibility.
