Reuters reported that first deliveries could be about three years after a contract is finalized, while an older-model loan, sale, or gift could move faster. Jonson said part of Sweden\u2019s aid budget for this year and next could potentially be used to help finance the purchase.<\/p>\n\n\n\n
Ukraine\u2019s Ministry of Defence framed the talks as more than an aircraft purchase. Its statement points to expanding defense industry cooperation, electronic warfare<\/a> work, radar, and satellite communications, plus a proposed \u201cBRAVE SWEDEN\u201d project tied to Ukraine\u2019s Brave1 defense innovation cluster.<\/p>\n\n\n\nReuters also reported that Saab\u2019s CEO hopes the agreement would become Sweden\u2019s biggest-ever arms export deal.<\/p>\n\n\n\n
War\u2019s environmental bill<\/h2>\n\n\n\n
It is easy to think of emissions as something tied to traffic jams and power plants, not a battlefield. But a 2024 report cited by Reuters estimated the invasion has produced about 193 million tons of CO2 equivalent once you include wartime emissions and expected reconstruction.<\/p>\n\n\n\n
A United Nations Environment Programme review warned that conflict can contaminate land and water through fires, industrial releases, and debris from destroyed infrastructure. <\/p>\n\n\n\n
The European Commission\u2019s Joint Research Centre<\/a> has also pointed to rising toxic pollution risks and serious soil impacts even when overall emissions fall because the economy slows.<\/p>\n\n\n\nSo why does an aircraft purchase sit in the middle of this? In practical terms, stronger air defenses<\/a> can help reduce strikes on refineries, chemical plants, and power networks, which are the kinds of hits that can snowball into long-term ecological harm. <\/p>\n\n\n\n\n\n\nAlso Read: Ukraine and five European partners just created a defense-buying coalition, and the hidden target is Russia\u2019s supply advantage<\/a><\/h4>\n<\/div>\n<\/div><\/div>\n<\/div>\n\n\n\nWhen the lights go out, it is not only the front line that feels it, it is also the family staring at an electric bill in a cold apartment.<\/p>\n\n\n\n

Fighter jets are never going to be \u201cgreen\u201d in the way an electric bus is green.
