Reflecting on Climate Achievements 2025: Key Environmental Milestones Around the World

Reflecting on climate achievements 2025, billions of people across the USA, Canada, the UK, and Europe celebrated major environmental wins—from record-breaking renewable energy use to landmark policy agreements.

Global Temperature & Climate Science Wins

• NOAA reported June 2025 as the third‑hottest June on record—evidence of enduring climate momentum and a call for urgent action.
• Despite La Niña’s cooling effect, January 2025 still recorded the highest global temperature for that month, 1.75°C above the pre-industrial level, according to the World Meteorological Organization.
• The Indicators of Global Climate Change 2025 infographic tracks key science‑based metrics like CO₂, sea level rise, and Arctic ice loss

Clean Energy Transition Milestones

USA & Canada

• In March 2025, renewables surpassed fossil fuels for the first time on the U.S. grid at 51% vs 49% energy mix, according to the League of Conservation Voters.
• Sun Prairie, Wisconsin, became the first US city to run entirely on 100% renewable energy for all public services.

UK & Europe

• The EU’s proposed “90 % GHG reduction by 2040” plan gained momentum ahead of a September summit
• The UK passed the Climate and Nature Bill, strengthening binding climate and ecological targets

Policy & Finance Highlights

• UN’s International Year of Glaciers’ Preservation launched March 21, with the Dushanbe Declaration protecting global water sources
• The IMO endorsed the first global greenhouse gas maritime fee starting in 2027, funding cleaner shipping technologies
• The Tropical Forest Forever Facility, a $125 billion fund for tropical forest conservation, targets launch at COP30

International Collaboration & Forecasts

• The first Climate Weeks in 2025 marked faster collaboration between governments, businesses, and communities.
• The WMO forecasts an 80% chance that at least one year from 2025-29 will exceed record highs, with an 86% probability that warming will exceed 1.5 °C above pre-industrial levels
• COP30 is scheduled for November 10–21 in Belém, Brazil, where key agreements like the Tropical Forest Forever Facility will be finalized
