On the eve of the United States\u0026#039; formal reentry into the Paris climate agreement on February 19, more than 50,000 people and nearly 200 global advocacy groups have signed a petition\u0026nbsp;demanding that President Joe Biden commit the country to doing its \u0022fair share\u0022 to combat the climate crisis.\u0022Out of the devastation of the coronavirus and the Trump administration, the president must seize this singular chance to build back a just, clean energy system that tackles the climate crisis and the wretched racism embedded in it.\u0022—Jean Su,Center for Biological DiversityThe petition is linked to a February 17\u0026nbsp;sign-on letter led by ActionAid USA, Center for Biological Diversity, Climate Equity Reference Project, Corporate Accountability, Friends of the Earth U.S., and N.C. Interfaith Power \u0026amp; Light, which \u0022represent millions of people across the United States who demand a climate just future, including youth, women, low-income communities, racially diverse communities, faith communities, and others.\u0022Noting that \u0022the United States has contributed more to climate change than any other country in the world\u0022 and that \u0022it is also the world\u0026#039;s wealthiest country, with much of this wealth being accumulated through activities that have directly or indirectly fueled climate change,\u0022 the letter stresses that the Biden administration must \u0022do its fair share in addressing this crisis.\u0022\u0022The people who voted for a better future are now ready to demand it from your administration,\u0022 it states. \u0022Amid a climate emergency that is wreaking unprecedented havoc, we write to you with an urgent request that is vitally important.\u0022\u0022We are calling upon you and your administration to walk the walk of real climate leadership,\u0022 urges the letter, which outlines a climate action plan with the goal of \u0022achieving the equivalent of a 195% reduction of greenhouse gas emissions below 2005 levels by 2030.\u0022\u0026nbsp;BREAKING - OVER 50,000 PEOPLE \u0026amp; 195 GLOBAL GROUPS DEMAND BIDEN COMMIT THE U.S. to do its “fair share” on climate! https://t.co/XslERe0eD4 \u0026lt;-@POTUS 2/17/21 https://t.co/HReqi8O5dZ @uscan @CANIntl #ParisAgreement #ActOnClimate #Faiths4Climate #Equity #JusticeFirst #ClimateFairShare— NCIPL (@NCIPL) February 17, 2021In order to accomplish such an ambitious reduction in emissions, the letter recommends:Cutting domestic greenhouse gas emissions by at least 70% below 2005 levels, by 2030, as part of a plan to decarbonize the entire economy as quickly as possible;Halting all new and phasing out existing fossil fuel extraction and justly transitioning the energy system to 100% clean and renewable energy; andAchieving the remaining 125% of the 195% reductions by directly supporting developing countries with the financial and technological assistance needed to reduce their emissions beyond what they can or should have to do on their own.\u0022After disproportionately polluting the planet for centuries, the United States must take its fair share of robust climate action on both the domestic and global stage,\u0022 said Center for Biological Diversity justice director Jean Su in a statement announcing the petition. \u0022While President Biden\u0026#039;s climate executive order is a strong first step, declaring a climate emergency will call this crisis what it is and level up the legal tools for confronting it.\u0022\u0022Out of the devastation of the coronavirus and the Trump administration, the president must seize this singular chance to build back a just, clean energy system that tackles the climate crisis and the wretched racism embedded in it,\u0022 Su added. \u0022The U.S. must help finance that same transition across the world in communities who have contributed the least to this climate emergency.\u0022This Friday the US officially re-enters the #ParisAgreement. But rejoining Paris isn’t enough. It’s time for @POTUS to make concrete commitments that the U.S. will do its #ClimateFairShareJoin the call: https://t.co/8CjQOjnCwY— Jean Su (@ajeansu) February 17, 2021Brandon Wu, director of policy and campaigns at ActionAid USA, said that \u0022just as domestic climate justice—a priority for the Biden administration—means a particular focus on historically marginalized communities, global climate justice means addressing legacies of exploitation and colonialism and their role in creating a tragically unjust climate crisis.\u0022\u0022People around the world are already suffering from devastating climate impacts, and many of those most vulnerable had little or no role in causing the problem,\u0022 Wu continued. \u0022As the world\u0026#039;s largest historical climate polluter, the United States has a moral and legal responsibility to support those vulnerable communities.\u0022\u0022The American people must begin a profound new conversation about global climate justice and about the U.S.\u0026#039; fair share in the shared global effort of stabilizing the climate system.\u0022—USCANThe petition and letter follow a December 2020 analysis by the U.S. Climate Action Network (USCAN), which laid out what it called a \u0022vision for equitable and ambitious climate action.\u0022\u0026nbsp;\u0022The American people must begin a profound new conversation about global climate justice and about the U.S.\u0026#039; fair share in the shared global effort of stabilizing the climate system,\u0022 asserted USCAN.In related news, Common Dreams reported last week that a new study by University of Washington researchers warned that countries must dramatically increase efforts to reduce planet-heating emissions in order to meet the Paris climate agreement\u0026#039;s less-than-ideal target of limiting temperature rise to 2°C by the end of this century.
