President Maithripala Sirisena planted a Na tree in the garden of the official residence of the British High Commissioner (Westminister House) to mark his last week as Commonwealth Chair-in-Office before he departs for CHOGM 2015 in Malta. President Sirisena held discussions with the British High Commissioner-James Dauris, regarding the this week’s Commonwealth Heads of Government Meeting (CHOGM), the UN Climate Change Conference (COP21) and other issues including Sri Lanka’s Progress in implementing the recommendations of the UN Resolution. In addition to reflecting Sri Lanka and the UK’s longstanding partnership in the Commonwealth, it also symbolizes the two countries’ commitment to green values. Under the Green is GREAT campaign, the UK Foreign and Commonwealth Office seeks to further a globally beneficial environmental agenda, stated the British High Commission in a press release. In September this year the UK made commitments to significantly increase climate finance over the next five years, providing at least £ 5.8 billion ($9 billion).
